Doppler confusion

Today, I'm one day shy of nine weeks and I was playing with my doppler this morning. I definitely faintly heard the heartbeat on both sides of my belly. The monitor showed readings ranging from 125-135, a couple times spiking to 140. So, if there are any nurses reading, can my pulse really be that high resting. I will admit, I get a little anxious before getting the doppler out, but I took my pulse before and after and it was about 105.

Anyway, since I was baffled finding readings on both sides of my belly, and I highly doubt it's twins, I looked up pulse points and here is the diagram I found. Now I'm confused as to whether or not I found the baby, or my pulse on the femoral artery. Not getting an early u/s this pregnancy is making me crazy. I just what to be able to say for sure there's a heartbeat. I know, I know, it's too early likely.
